Definitions

  • the invention relates to a system for destroying documents that have already been shredded by a document shredder or a system of a number of document shredders.
  • the system includes central collecting means for shredded documents.
  • central collecting means could be a pipe system or the like.
  • One example of such central collecting means is described in DE 199 34 818 A1, which is incorporated into the text of the description by explicit reference.
  • Burning means are arranged together with the collecting means. This can be done in such a way that the collecting means lead to the burning means.
  • the burning means can have one burning chamber or a number of burning chambers for burning shredded documents.
  • the burning chamber again is connected with outlet means for the remains, or ash, of said shredded and burned documents.
  • Such a system provides a secure way for collecting shredded documents in that the documents are collected centrally, and then burned. As the documents are usually made of paper, they can easily be burned.
  • the burning means and the burning chamber can be adapted for burning shredded documents in a continuous process.
  • Such a continuous process particularly for larger systems with a number of document shredders, allows the shredded documents to keep coming as they are being shredded.
  • the burning of shredded documents cannot only be continuous, but also with no delay between shredding and burning.
  • the burning means and the burning chamber are adapted for burning shredded documents in a non-continuous process, for example step-wise.
  • shredded documents can be collected to a certain amount or for a certain period of time and then burning is started. Collecting of shredded documents can be at any convenient place. For example, they are collected in the burning chamber itself. During such a collecting period burning should be stopped.
  • burning should be stopped.
  • Such a system is especially advantageous if the number of shredded documents is not so great or if they are not supplied continuously.
  • the burning chamber can be an elongated channel. This provides a certain distance for shredded documents to pass through the burning chamber for better, more efficient, secure and complete burning.
  • the burning chamber can, for example, be in the form of a pipe or the like.
  • the burning chamber can be equipped with burners.
  • the burners can be gas burners. They can produce flames reaching into the burning chamber. The burning shredded documents can then be collected in or pass through the burning chamber. Gas burners are efficient and can be started easily and quickly. Of course other kinds of burners can be used within the scope of the invention.
  • Heating means can be installed in the burning chamber itself or surrounding the burning chamber.
  • This method with an embodiment of a burning chamber being free of heating means or the like on the inside the system is very simple and secure in operation.
  • Heating means especially for arranging on the outside of the burning chamber and heating the burning chamber on the inside, can also incorporate electric heaters. Such electric heaters reduce the risk of explosions or fires by hazardous fuels.
  • the burning chamber can be connected with an exhaust system.
  • the outlet means of the burning chamber can be connected with such an exhaust system.
  • the system or the outlet means can be connected to a separator filter.
  • a filter or filter unit is preferably used for cleaning the exhaust air.
  • the filter can be a fine filter unit.
  • the collecting means may include a vacuum stage and a pipe system.
  • the pipe system is connected to a number of document shredders.
  • the vacuum stage is adapted for transporting or guiding shredded documents from the document shredders to the collecting means or the burner.
  • Such a vacuum stage can be positioned after the burning means in the way shredded documents are taking after shredding. By this a vacuum stage can also be adapted for transporting remains of shredded documents leaving the burning chamber further along the system.
  • FIG. 1 shows a schematic view of a system 11 for shredding and burning documents.
  • the system 11 comprises document shredders 13 being arranged as a plurality in a building or the like.
  • the document shredders 13 are connected with collecting means 15 via a pipe system 16.
  • the pipe system 16 is made up of a central pipe and several pipes leading from the central pipe to the document shredders 13 in a branch-like manner.
  • the collecting means comprise burning means 17 with a burning chamber 18 and a burner 19 or similar burning devices.
  • the central pipe 16 leads into the burning chamber 18.
  • the burning chamber 18 With an outlet 20 the burning chamber 18 is connected to a fine filter unit 22 used for filtering the exhaust air of the burning chamber, specifically respective to ash or the like.
  • a fine filter unit 22 is common in the art and needs not to be described in detail.
  • the fine filter unit 22 could also be replaced by similar filtering means with the same functionality.
  • the fine filter unit 22 is connected via pipes to two vacuum units 24. These vacuum units 24 function as a means for transporting shredded documents from the document shredders 13 through the pipe system 16 to the burning means 17 and then to the fine filter unit 22. Furthermore, the vacuum units 24 are connected to an air exhaust 26. Such an air exhaust is also known in the art and needs not to be described in detail.
  • a compressor system could be provided which could be switched upstream of the pipe system 16. Using such a compression means pressurized air can be blown into the document shredders and the pipe system 16 to further enforce the shredded documents through the pipe system 16.
  • Burning chamber 18 is pipe like and runs substantially in a horizontal position. On the left, the burning chamber 18 is connected to the pipe 16. On the right, burning chamber 18 is connected to the outlet means 20 in the form of another pipe.
  • burners 19 are mounted.
  • the burners 19 are gas burners 29 which reach into the burning chamber 18.
  • the gas burners 29 are connected to a gas pipe 30 and a gas valve 31 for turning on or off the gas.
  • the gas burners 29 produce a plurality of flames in the form of a row or a field covering a certain area.
  • Shredded documents 28 falling into burning chamber 18 from pipe 16 are transported through the flames 32, catch fire and are burned till they are ash 34.
  • the ash 34 is then removed out of the burning chamber 18 by way of the outlet means 20.
  • gas burners or other burning means producing flames can be arranged in many ways.
  • Burning chamber 18 is constructed similarly to the one in Figure 2. Instead of gas burners 29, an electric heater 36 in the form of a long pipe is provided. The electric heater surrounds the burning chamber 18 in screw-like manner. Alternatively, it is possible to provide an electric heater substantially underneath the burning chamber 18 or even inside the burning chamber 18.
  • the electric heater 36 is connected to electric connectors 37 which have a similar function to gas valve 31 in Figure 2. Via the connectors 37 the electric heater 36 can be energised.
  • the ash 34 is removed through outlet means 20 to the filter unit 22.
  • the burning means 17 illustrated in Figures 2 and 3 are adapted for burning shredded documents in a continuous process. For burning shredded documents in a non-continuous process, it is possible to collect a certain amount of shredded documents in a position located prior to the burning chamber 18. After having collected a certain amount of shredded documents they can be transported into the burning chamber 18b and be burned.
